IINITE STATES P TENT Orrictio LUTHER B. BAILEY, OF LONDON, ONTARIO, CANADA.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 308.400, dated November 25, 1884.

Application filed May 28, 1884, (No modeli) To aZZ whom it may concern.-

Be it known that I, LUTHER B. BAILEY, of London, in the county of Middlesex and Province of Ontario, Canada, have invented new and useful Improvements in Lubricators; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, which forms a part of this specification.

This invention relates to certain new and useful improvements in lubricators, by means of which the regular feed of the oil maybe discerned, and wherein the oil is conducted down the sides of the transparent feed-tube, in contradistinction to other devices similarly located, and for a similar purpose, wherein the flow of the oil is indicated by drops falling intermittently through the tube; and the invention is designed as an improvement on'the device patented to me May 20, 1884, and numbered 298,813; and it consists in the peculiar construction and arrangement of parts whereby more perfect means are provided for seeing clearly the feed of the oil in a thin film or sheetas it passes down the inner sides of the transparent tube, all as hereinafter more fully described and claimed.

In the accompanying drawing, which forms a part of this specification, A represents a section of the visible feed-support in the form of a coupling, through the center of a hollow sphere terminating at top in an interiorly-threaded socket, B, which incloses an elastic packing, a, which forms a tight joint between the glass tube 0 and the socket B, the hollow nut D being screwed down to expand and force the packing a to perform the functions required of it. The lower portion of this part A also terminates in an interiorly-threaded socket, E, and this portion is provided with an elastic packing, b. The hollow and eXteriorly-threaded plug F, provided with a flange, G, is screwed into the socket E until its inserted end engages with the packing b and compels it to perform its function at this point. The projecting end of the hollow plug F forms means of connecting this device to the part to be lubricated.

The interiorly-threaded socket B at the top with reflectors.

forms the means for securing this device to the bottom end of a lubricator and with the delivery-tube H thereof, (which is shown in dotted lines in the drawing,) such deliverytube being in its internal diameter as large, or nearly so, as the internal diameter of the transparent tube 0.

I am aware of the Patent N 0. 106,150, wherein a similar transparent tube is employed in connection with a lubricator, the delivery end of which is so formed as to compel the oil to assume the form of a drop and pass then down through the center of the sight-feed; and it is specially at this point where I make my improvement, so that the oil delivered from the delivery-tube, passing down its interior sides, flows in the same manner uninterruptedly through the glass tube, showing itself in a film in contradistinction to the drop. The coupling forming the body of this device is thick enough in a section transverse to the section shown in the drawing to allow of the formation of the apertures leading into the sockets B and E within its walls, leaving the center portion open and free to the seat. The interior of this ring formation of the coupling-sector is polished, thereby forming on two opposite sides of the transparent tube curved reflectors, which will facilitate the examination when the oil is flowing more thickly down the adjacent sides of the transparent sides of the tube than it is down the two opposite sides, which are unprovided This device may be constructed, as described, to be attached to the lower end of a lubricator, or it may be socured integral thereto, if preferred. By the construction and employment of a device of this character the certainty of the feed under all circumstances may be examined without difficulty, and its construction is so simple that it adds but a trifle in the amount of the cost of the lubricator.

I am aware of Patent No. 27 7 ,464, and make no claim to the construction shown therein.

What I claim as my invention is-.

1. The combination, with the transparent tube of a lubricator, of a surrounding casing partially surrounding the same, and provided with a curved polished surface to reflect and condense the rays of light, substantially as described.

2. The coupling A, provided with passages through the axis of the same, and formed with 5 recesses, and adapted to hold in place a tube,

in combination with the transparent tube 0,

secured in said passages, the interior of the ring formation of said coupling being polished to form reflectors, substantially as and for the purpose specified.
